The first round was a written test that included standard quantitative questions and Java technical questions.

Following that, there were two rounds of personal interviews: one with the manager and another with a senior technical person.

My interview with the manager was conducted first and went very well. They asked general managerial questions and also requested me to solve one of the puzzles from the written test technically in Java.

The subsequent technical round focused on normal Java questions. If you have prepared for the SCJP exam, you should be able to answer all the questions easily. I was only unable to answer one or two questions, and that was primarily because I hadn't prepared specifically for the interview or reviewed Java in a long time.
